OVERLAP DENSITY (OD) HEATMAPS AND CONSENSUS DATA DISPLAYS

摘要

Systems and methods that generate or provide overlap displays of multiple sets of data in a manner that advantageously simplifies trend visualization in large sets of data. A 2-dimensional occurrence count array is generated for a plurality of similar data sets. Each element in the array is a number of times a corresponding pair of data values x, y occurs in the plurality of N data sets, wherein each array element corresponds to a discrete interval of x and y data values. Once the array has been generated, a graphical display of overlap density may be generated by comparing a desired percentage of overlap with the value of each array element. Those array elements having values that satisfy the desired percentage of overlap are rendered, as a display object, using one or more colors, shades and/or patterns representing varying degrees of overlap percentage.
